Abstract
The enantioselective crotylation of aldehydes with 1,2-diaminochlorocrotylsilane reagents is effectively catalyzed by Sc(OTf)(3). The one significant limitation on the utility of these reagents--substrate scope--has thus been addressed. The net result is the most comprehensive and highly practical method for enantioselective aldehyde crotylation yet advanced.
摘要
手性烯丙基硅试剂与醛的对映选择性 crotylation 反应可有效地被 Sc(OTf)(3) 催化。这些试剂的一个显著的局限性——底物范围——因此得到了解决。最终得到了迄今为止最全面和最实用的对映选择性醛 crotylation 方法。
